For me anatomy was seprate from Human Physiology, then pathophys.
Anatomy was easier to grasp than Physiology, anatomy was more memorization, as the previous poster noted such as bones, tissues, arteries, organs(ie chambers of the heart, lobes of the lung), anatomy of the brain, spine, pia, dura matter etc. Also in anatomy we learned the cranial nerves, I mean this was over two years ago, so what I remember.
Physiology was much more difficult. We had six sections I think, with cardio, neuro, respiratory, renal, GI, endocrine/repro.
The MOST difficult were respiratory and renal. The equations can be aggrivating, such as Total Lung Volume, Pulse Pressure, Total Reisdula Volume, ummm Glomerular Filtration Rate, etc. I could go on
You really need to pay attention to grasp the physiology, it was not like anatomy where you could learn from the book as easy.
Also, my word of advice, pay attention now. These classes will come back, better you know it all now then in two years you are expected to already know explicit anatomy/physio when taking health assessment.
Don't worry too much about patho, we to me anyway it was sooo much easier.
Don't worry about studying now, you will get all the info you need to know in a few weeks.
